单选题In the past few decades, remarkable findings have been made in ethology, the study of animal social behavior. Earlier scientists had (21) that nonhuman social life was almost totally instinctive or fixed by genetics. Much more careful observation has shown that (22) variation occurs among the social ties of most species, showing that [earning is a part of social life. That is, the (23) are not solely fixed by the genes. (24) , the learning that occurs is often at an early age in a process that is called imprinting. Imprinting is clearly (25) instinctive, but it is not quite like the learning of humans, it is something in between the two. An illustration best (26) the nature of imprinting. Once, biologists thought that ducklings followed the mother duck because of instincts. Now we know that. shortly (27) they hatch, ducklings fix (28) any object about the size of a duck and will henceforth follow it. So ducklings may follow a basketball or a briefcase if these are (29) for the mother duck at the time when imprinting occurs. Thus, social ties can be considerably (30) , even ones that have a considerable base (31) by genetics. Even among the social insects something like imprinting (32) influence social behavior. For example, biologists once thought bees communicated with others purely (33) instinct. But, in examining a "dance" that bees do to indicate the distance and direction of a pollen source, observers found that bees raised in isolation could not communicate effectively. At a higher level, the genetic base seems to be much more for an all-purpose learning rather than the more specific responses of imprinting. Chimpanzees, for instance, generally (34) very good mother but Jane Goodall reports that some chimps carry the infant. upside down or (35) fail to nurture the young.

单选题 It never rains but it pours. Just as bosses and boards have finally sorted out their worst accounting and compliance troubles, and improved their feeble corporation governance, a new problem threatens to earn them--especially in America--the sort of nasty headlines that inevitably lead to heads rolling in the executive suite: data insecurity. Left, until now, to odd, low-level IT staff to put right, and seen as a concern only of data-rich industries such as banking, telecoms and air travel, information protection is now high on the boss's agenda in businesses of every variety. Several massive leakages of customer and employee data this year--from organizations as diverse as Time Warner, the American defense contractor Science Applications International Corp and even the University of California. Berkeley--have left managers hurriedly peering into their intricate 11 systems and business processes in search of potential vulnerabilities. "Data is becoming an asset which needs no be guarded as much as any other asset." says I am Mendelson of Stanford University's business school. "The ability guard customer data is the key to market value, which the board is responsible for on behalf of shareholders". Indeed, just as there is the concept of Generally Accepted Accounting Principles (GAAP), perhaps it is time for GASP. Generally Accepted Security Practices, suggested Eli Noam of New York's Columbia Business School. "Setting the proper investment level for security, redundancy, and recovery is a management issue, not a technical one." he says. The mystery is that this should come as a surprise to any boss. Surely it should be obvious to the dimmest executive that trust, that most valuable of economic assets, is easily destroyed and hugely expensive to restore--and that few things are more likely to destroy trust than a company letting sensitive personal data get into the wrong hands. The current state of affairs may have been encouraged--though not justified--by the lack of legal penalty (in America, but not Europe) for data leakage. Until California recently passed a law, American firms did not have to tell anyone, even the victim, when data went astray. That may change fast lots of proposed data-security legislation now doing the rounds in Washington. D. C. Meanwhile, the theft of information about some 40 million credit-card accounts in America, disclosed on June 17th, overshadowed a hugely important decision a day earlier by America's Federal Trade Commission (FTC) that puts corporate America on notice that regulators will act if firms fail to provide adequate data security.
